okay so like, welcome to the glow-up of nfsd_net_cb_shutdown(9), a kernel API page that lives in the Kernel API Manual and honestly deserves main character energy. it's short, it's sweet, it's giving "cleanup era" ✨

🌸 NAME 🌸

nfsd_net_cb_shutdown — release per-netns callback RPC program resources 💖

like, it's the friend who shows up at the end of the party to help you pack up. no cap.

---

✨ SYNOPSIS ✨

void nfsd_net_cb_shutdown (struct nfsd_net *nn );

that's it. that's the whole vibe check. one function, one argument, zero drama 🫶

---

🦋 ARGUMENTS 🦋

• nn — the NFS server network namespace 🌈 literally the netns we're shutting down for. that's the whole assignment, bestie.

---

💜 DESCRIPTION 💜

Frees resources allocated by nfsd_net_cb_init.

periodt. 💀 that's the entire description and honestly? icon behavior. nfsd_net_cb_init did the allocating, nfsd_net_cb_shutdown does the freeing — they're a matched set, a duo, the callback RPC program resource equivalent of a friendship bracelet. 🎀

so when you call nfsd_net_cb_shutdown, what you're doing is releasing those per-netns callback RPC program resources that were handed out earlier. clean up after yourself, queen 👑
